Kawiwan flat is very well located, near to the BTS station in a very quite and residential area in Bangkok.
The place is small but will all that you need for a pleasure stay in bangkok (I must add also that is very fictional and well furnished). The only negative thing is about the highway: is very close, but as far as I could understand this is the price you have to pay if you want to be in a central area of Bangkok. This small defects is well compensated by the swimming pool(amazing) at the same floor where you cab enjoy an awesome city view.
Really guys: if you needs to spends some days in Bangkok you will love this pace, is perfect!
